I get a lot of emails from palm tree owners, asking for advice on how to save cold-damaged palm trees. In my previous article, called Palm Tree Cold Protection, I’ve outlined few steps you can take to protect your palm trees before freezing temperatures are reached. Today, I will tell you, what you need do to save your cold-damaged palms.

The most important and the most vulnerable part of the palm tree is the bud. Bud is where new leaves emerge. If the bud tissue of the palm has NOT been severely damaged, the palm should recover and start producing new leaves during the following summer. New emerging leaves might be deformed, partially brown or have other abnormalities. It might take from 6 months to one year from the freeze for the palm tree to recover. If the bud tissue has been severely damaged, the palm might not survive.

Step 1: Determine level of injury

First, you need to determine the level of injury. To see how extensive the damage is, gently pull newly emerging spear. Sometimes, new spear is very loose and pulls out easily. Check to see if the bud is still alive. If it is green, the palm tree can be saved.

Step 2: Pruning

Next, prune only dead branches and remove all the dying leaves around the bud, so it can dry out. Don’t cut back leaves with brown tips, since palms still extracts nutrients for new leaves from dying fronds. Be careful not to over-prune. The more green leaves you remove, the less food the palm can produce. Pruning too many leaves will only add to the stress.

Step 3: Liquid Copper

After the stress from the freeze, palm trees become more vulnerable to bacterial and fungal infections. Copper Fungicide has a unique formula that helps fight both. It should be applied no more than twice, 10 days between each application. Drench the bud of the palm with liquid copper using the force of the spray to clean it. This should reduce the chances of bud rot due to microorganisms.  Cold Damaged Palm Tree Care

Applying Copper Fungicide around the base of the palm will suppress development of the root diseases. One of the products I found to be very effective is Bonide Products Copper Fungicide. It works very well against fungi and bacterial.  Since it’s made from natural product you can use it for organic gardening.

Step 4: Fertilizing

Few words about fertilizing. Do NOT fertilize your palm trees right away, wait until late summer or fall. Most people start fertilizing as soon as they see brown leaves. Fertilizer is NOT plant food. Despite it saying “Palm Food” or “Plant Food” on the labels, fertilizer is a mixture of nutrients used to make soil more fertile and promote plant growth. Plants produce their own food, using water, carbon dioxide and solar energy. Think of the fertilizers as vitamin supplements. You can’t make a sick, diseased, malnourished person healthy with vitamins. When you start fertilizing your sick palm tree, you are asking it to start growing, which creates even more stress on the poor tree. Wait till late summer or spring and apply slow release fertilizer.
